Title
(EN) CALIBRATION-BASED TOOL CONDITION MONITORING SYSTEM FOR REPETITIVE MACHINING OPERATIONS
(FR) SYSTÈME DE SURVEILLANCE D'ÉTAT D'OUTIL À BASE D'ÉTALONNAGE POUR OPÉRATIONS D'USINAGE RÉPÉTITIVES
Abstract
(EN)
A real-time calibration-based tool condition monitoring system, device and method for repetitive machining operations to monitor tool conditions by a combination of a calibration procedure using a reference tool and similarity analysis comparing the reference tool with a working tool is disclosed.
(FR)
L'invention concerne un système, un dispositif et un procédé de surveillance d'état d'outil à base d'un étalonnage en temps réel pour des opérations d'usinage répétitives afin de surveiller des états d'outil par une combinaison d'un processus d'étalonnage à l'aide d'un outil de référence et d'une analyse de similarité comparant l'outil de référence à un outil de travail.
